1.5 GNSS

1.5.1 GPS u-blox PAM-7Q receivers are designed to receive and track the L1C/A signals provided at 1575.42 MHz by the Global Positioning System (GPS).

1.5.2 QZSS The Quasi-Zenith Satellite System (QZSS) is a navigation satellite overlay system for the Pacific region covering Japan and Australia that transmits additional GPS L1C/A signals. PAM 7Q positioning modules are able to receive and to track these signals simultaneously with GPS, resulting in better availability, especially under bad signal conditions e.g. in urban canyons.

1.6 Augmented GPS

1.6.1 Assisted GPS (A-GPS) A-GPS improves GPS performance by delivering aiding data to the GPS receiver via wireless networks or the Internet. Supplying information such as ephemeris, almanac, approximate last position, time and satellite status and an optional time synchronization signal significantly reduces Time to First Fix (TTFF) and improves acquisition sensitivity.

AssistNow Online and AssistNow Offline are u-blox’ end-to-end A-GPS services for devices with or without network connectivity. AssistNow Online and AssistNow Offline can either be used alone or in combination. They are very easy to implement, require no additional hardware, and generate virtually no CPU load. PAM-7Q modules support u-blox’ AssistNow Online, AssistNow Offline and AssistNow Autonomous A-GPS services, and are OMA SUPL compliant.

AssistNow Online

With AssistNow Online, an internet-connected GPS device downloads assistance data from u-blox’ AssistNow Online Service at system start-up. AssistNow Online is network operator independent and globally available.

u-blox only sends ephemeris data for those satellites currently visible to the device requesting the data, thus minimizing the amount of data transferred.

PAM-7Q - Data Sheet


of 23

AssistNow Offline

With AssistNow Offline, users download u-blox’ Differential Almanac Correction Data from the Internet at their convenience. The correction data can be stored in the memory of the application processor. Therefore, the service requires no connectivity at system start-up and enables a position fix within seconds, even when no network is available.

1.6.2 AssistNow Autonomous AssistNow Autonomous provides functionality similar to Assisted-GPS without the need for a host or external network connection. It is an embedded feature available free-of-charge that accelerates GPS positioning by capitalizing on the periodic nature of GPS satellite orbits. GPS orbit predictions are directly calculated by the GPS receiver and no external aiding data or connectivity is required. AssistNow Autonomous can be used alone, or together with AssistNow Online or AssistNow Offline for increased positioning speed and accuracy.

For more details see the u-blox 7 Receiver Description Including Protocol Specification [1].

1.6.3 Satellite-Based Augmentation System (SBAS) PAM-7Q positioning modules support SBAS. These systems supplement GPS data with additional regional or wide area GPS augmentation data. The system broadcasts augmentation data via satellite, the data which can be used by GPS receivers to improve the resulting GPS precision. SBAS satellites can be used as additional satellites for ranging (navigation), further enhancing precision. The following SBAS are supported with PAM-7Q: WAAS, EGNOS and MSAS.

For more details see the u-blox 7 Receiver Description Including Protocol Specification [1].

1.7 TIMEPULSE A configurable time pulse signal is available with PAM-7Q modules.

The TIMEPULSE output generates pulse trains synchronized with GPS or UTC time grid with intervals configurable over a wide frequency range. Thus it may be used as a low frequency time synchronization pulse or as a high frequency reference signal.

By default the time pulse signal is configured to 1 pulse per second. For more information see the u-blox 7 Receiver Description including Protocol Specification [1].

1.8 Protocols and interfaces

Protocol Type

NMEA Input/output, ASCII, 0183, 2.3 (compatible to 3.0)

UBX Input/output, binary, u-blox proprietary

RTCM Input, 2.3

Table 2: Available Protocols

PAM-7Q is a GPS only module with one UART and one I2C interface. Some features mentioned in u-blox 7 Receiver Description Including Protocol Specification [1] might not supported by PAM-7Q because of unsupported interfaces.

All protocols are available on UART and DDC (I2C compliant). For specification of the various protocols see the u-blox 7 Receiver Description Including Protocol Specification [1].

1.9 Interfaces A number of interfaces are provided either for data communication or memory access. The embedded firmware uses these interfaces according to their respective protocol specifications.

PAM-7Q - Data Sheet


of 23

1.9.1 UART PAM-7Q modules include one UART interface, which can be used for communication to a host. It supports configurable baud rates. For supported baud rates see the u-blox 7 Receiver Description Including Protocol Specification [1].

1.9.2 Display Data Channel (DDC) An I2C compliant DDC interface is available for communication with an external host CPU. The interface can be operated in slave mode only. The DDC protocol and electrical interface are fully compatible with the Fast-Mode of the I2C industry standard. Since the maximum SCL clock frequency is 400 kHz, the maximum transfer rate is 400 kb/s.

The DDC interface is I2C Fast Mode compliant. For timing parameters consult the I2C standard.

The maximum bit rate is 400 kb/s. The interface stretches the clock when slowed down while serving interrupts, so real bit rates may be slightly lower.

1.10 Clock generation

1.10.1 Oscillators PAM-7Q GPS modules are available in TCXO version. TCXO option allows accelerated weak signal acquisition, enabling faster start and reacquisition times.

1.10.2 Real-Time Clock (RTC) The RTC is driven by a 32 kHz oscillator, which makes use of an external RTC crystal. If the main supply voltage fails and a battery is connected to V_BCKP, parts of the receiver switch off, but the RTC still runs providing a timing reference for the receiver. This operating mode is called Hardware Backup Mode, which enables all relevant data to be saved in the backup RAM to allow a hot or warm start later.

1.11 Power management u-blox PAM-7Q technology offers a power optimized architecture with built-in autonomous power saving functions to minimize power consumption at any given time. Furthermore, the receiver can be used in two operating modes: Continuous mode for best performance or Power Save Mode for optimized power consumption respectively. In addition a high efficiency DC/DC converter is integrated to allow low power consumption even for higher main supply voltages.

1.11.1 DC/DC converter PAM-7Q modules integrate a DC/DC converter, allowing reduced power consumption by up to 50% especially when using a main supply voltage above 2.5 V.

For more information see the PAM-7Q Hardware Integration Manual [2].

1.11.2 Operating modes PAM-7Q modules have two operating modes:

• Continuous Mode for best GPS performance

• Power Save Mode to optimize power consumption

PAM-7Q - Data Sheet


of 23

1.11.2.1 Continuous Mode

Continuous Mode uses the acquisition engine at full performance resulting in the shortest possible TTFF and the highest sensitivity. It searches for all possible satellites until the almanac is completely downloaded. The receiver then switches to the tracking engine to lower power consumption.

Thus, a lower tracking current consumption level will be achieved when:

• A valid GPS position is obtained

• The entire almanac has been downloaded

• The ephemeris for each satellite in view is valid

1.11.2.2 Power Save Mode

For power sensitive applications u-blox PAM-7Q receivers provide a Power Save Mode for reduced power consumption.

Power Save Mode provides two dedicated methods called ON/OFF and Cyclic tracking, that reduce average current consumption in different ways to match the needs of the specific application. These options can be set by using a specific UBX message.

For more information about power management strategies, see the u-blox 7 Receiver Description Including Protocol Specification [1].

1.12 Antenna PAM-7Q modules are designed with integrated 18 x 18 mm patch antenna provides RHCP polarization. PAM-7Q antenna modules are relatively wideband and tuned a few MHz above L1, customer housing (plastic) usually will de-tune center frequency back to L1.

Figure 2 illustrates the normalized patch antenna gain for PAM-7Q.

In order to maintain good performance for the on-board patch antenna of the PAM-7Q, some design rules should be followed. For more information see the PAM-7Q Hardware Integration Manual [2].

7.2 Shipment, storage and handling For important information regarding shipment, storage and handling, see the u-blox Package Information User Guide [3].

7.2.1 Hand soldering For detailed instructions concerning hand soldering, see PAM-7Q Hardware Integration Manual [2].

PAM-7Q modules are hand soldering devices, Moisture Sensitivity Level (MSL) is therefore not applicable.

7.2.2 Antenna ageing Antenna electrode metallization is unprotected silver and will tarnish during storage due to sulphuric compounds present in the atmosphere. Elevated temperature and humidity will accelerate this process. Human skin contact, wool etc. will also cause tarnishing. This has no effect on the electrical performance of the antenna. u-blox accepts no warranty claims for tarnished products due to this normal and to be expected process.

7.2.3 ESD handling precautions

PAM-7Q modules are Electrostatic Sensitive Devices (ESD). Observe handling precautions! Failure to observe these precautions can result in severe damage to the GPS receiver!

GPS receivers are Electrostatic Sensitive Devices (ESD) and require special precautions when handling. Exercise care when handling patch antennas, due to the risk of electrostatic charges. In addition to standard ESD safety practices, take the following measures into account whenever handling the receiver:

• Unless there is a galvanic coupling between the local GND (i.e. the work table) and the PCB GND, then the first point of contact when handling the PCB must always be between the local GND and PCB GND.

• Before mounting an antenna patch, connect ground of the device

• To prevent electrostatic discharge through the RF input, do not touch any exposed antenna area. If there is any risk that such exposed antenna area is touched in non ESD protected work area, implement proper ESD protection measures in the design.

• When soldering to the receiver’s I/O connections, make sure to use an ESD safe soldering iron (tip).
